Sumitron marketing provides peristaltic pump dispensers [model ppd-130] from i&j fisnar inc, usa. These pump dispensers provide volumetric dispensing of low viscosity materials, such as cyanoacrylates, oils and solvents without the heed for compressed air. They use peristaltic pump technology to dispense material directly from its original packaging. By eliminating the need to transfer the material from its original, the risk of material contamination and operator contact is reduced. The suck-back feature reverses the pump after dispensing to prevent material from dripping between cycles and also allows the material tube to be emptied when dispensing is complete. Dispensed amounts may be controlled manually or with the built-in timer. Maintenance and clean up are simple because the material never comes in contact with the dispensing mechanism.
